it known iilzai; Lila-X1 1 GUILLERY, a citizen of rlie Republic of France residing at 103 Avenue (is la Hepnh'liqne, Anheryi'lliers, Seine, in the French Republic, have invented certain new and useful linprovei'nents in the Admission and Exhaust l /lechanisin for Engines, of which the 'i'ollowing is a specificaifzion.

This axial movement of the distributer may be proclucecl intermittently, at proper intervals, by amechanism which impartsto the clistributer such an axial movement ofclefinite extent regardless or the 'ciegreeof opposition to angular developed by the friction'al engagement. In the preferred form of thefinvention, however, the arrangement is such that the axial movement of the distributer is brought about by a component ofeiiort applied to the v alve stein. That is to say, the turning ei'fort applied to the stem of the distribmier is, by a suitable mechanism, divided into one component tending to impart angular displacement to the stem, and a second component at right angles to the first and tending to impart an axial increment to the stem and conseforce, then the axially directed compenena of thatiorce will l'ieco'n'ie effective to more the (lisuributer very slightly in an axial (lirection until the resistance due to ilie 'lrim iiional engagement is sufficiently reduced to? permit the iangentially af plie lcomponent of the force to effect the desirul angular displacement.

ol' the inclines of the worm drive. is a vertical section particularly showing the driving connection between the engine I shaft and the distributor.

1n the construction illustrated in Fig. l, the cylinder (1 end. at its upper part in a frustowonical head into which the exhaust orifices c and admission orifices d open; any desired number of these may be provided.

95 The distributor b fits thefrusto-conical head; its stein issues from the cylinder and it comprises ports 6 for the exhaust c and ports f for the admission (Z. By a 'reciproeating movement of rotation this distributor so I) is thus able -to present its ports (2 or f in front of the exhaust orifices c or admission orifices (Z attl e appropriate phases of the motor cycle. A lever g is iixed to the stem of the distributor and is given a horizontal reeiprbcating movement by a globular cam in in which a groove is formed appropriately to the phases of the cycle- .A ball bearing 2' is acted upon by a spring in such a manner as to provide a good joint for the distributor b in the frusto-conicalcylinder head which serves as its, scat. 'At the upper part of the distributor stein a lever is arranged and is separated from the lever g by a ball bearing. This lever carries a threaded rod which is. housed in a nut Z fixed to the body of the cylinder and is subjected to the action of a lateral thrust spring' A: (Fig. 3) whichowing to its action in conunction \\li,li that ofthe screw tends to cause the said l'ever 7' to rise, its roller being displaced and guided by theextreine path in of the cam (Fig. 5). The distributing gem-as a whole is arranged in a car case and suitably lubricated; the seat ot the distrihuter lg neednot be lubricated because as hereinafter OXDllllllOd its angular d splacemcuts take place after disengagement between the movable element and the cylinder head which terms the seat. The gnition talces place in the ordinary manner (by means of a sparking plug arrangcdlon a boss on the 'linder a for example) and the cooling water circulates around the stem and the seat of the distributor.

This device acts in the following manner.

The came it is arranged in such a manner that it imparts no displacement to the distributor 6 during the compression and'expansion phases during which periods is subjected to eflorts directed parallel with its axis of rotation and which tend to wedge it in the cylinder head which serves as its seat. At the moment at which the distribu-i ter 1) is to receive an angular displacement so as to uncover. the exhaust orifices 0 or the admission orifices d, the edge m of the cam imparts to the lever j a horizontal movement of oscillation which owing to the'screvi' is transformed into a helicoidal movement causing it to be applied to the distributor b. The distributor is disengaged from its seat in such a manner that owing to its groove thecam [M62111 displace the lo er 9' thereby impartii'ig to it the :ngi; ir movementnecessary for producing the corresponding phases of the distribution. When the cam It has returned the lever g to its initial po sition and the distributor-1) is in the position for closing the admission orifices d and the} exhaust orifices c the spring acts upon the i lever 3' so as to cause it to accompany the I path at of the cam it which enables the said distributer I) to form a close joint with its seat. 111 this construction it will be noted that the distributerb is disengaged periodicall and at predetermined times having regard to the form of the groove in the cam iiand to the phase of the cycle. by an active effort; this action is obtained by a 1necliani-' cal control and by a special actuating mem- 10!) her (the path m7 of the cam ii) suitably shaped with this object and'acting so as to produce the disengagement prior to the angular displacement whatever the efforts exerted during the contact of the superposed walls may be.

in the construction illustrated in Fig. 7 the rod of the distrihuter I) is invariably connected with a claw-'1) and its extremity is housed in the bm'e of another claw p carryno ing a lateral lever' q. The upper extension of this claw 1) turns in a plug it adjustable in the cylinder and forming a. stop. Ball bearings are arranged brtneen the moving surfaces and facilitate the oscillations pro (lured by the vcam r. The lingers oi the claw o penetrate between the lingers of the claw 71 leaving a lu'ogressive lateral clearance t on each side and the groove in the cam r is suitably formed .(the portion a) for v' taking this play into aecamnt. The disengagement oi the distributor b is thus rendered automatic and is produced by a. passive etlort that is to say by the resistance opposed-by the distrihuter I) to its angulag'il displacement as a result of the wedging 1;; tained by the ell'orts produced upon it during the compression and the expansion. Whenthe lever I acted upon by the cam 1' begins its moveinent=of oscillation the 1111- 1 gels of the claw p constitute inclined coi-clal planes relatively to tli'e fingers i claw 0 and ii" the value of the. adherence lystvreen the ilisti'i i'uteir Z) and its sent is went than the tang (11kmllydirected conipgneni o (lisl ll? the force appl'ed tlunugliitlie lever 9* am the o'i'mt the inclined plnnPs (if the claw y) lzl'ieii the nits 1 .ii'ie [lair ilis'plzicumonu of the distri ital 'Wli i, i c) lit if the fillll! 1 liel'encclmimm: Hie llhil'illlitfil :uiu it; sent greater tum the tangentially directed cunipummt of the applied force. than the axially (iii acted con'iponum 0f the upplii d force \i'ill impar'i' to the claw 0 ill axial 1 niovm'nent, which precedes film angular (livpiucon'mit.
